Answer:
769/70
Step-by-step explanation:
5 2/7 = 37/7
5 7/10 = 57/10
The lowest common multiple is 70
37*10/(7 * 10) = 370/70
57/10 = 57*7/(7*10) = 399/70
Now add
370/70 + 399/70
769/70

Answer:
31 ft
Step-by-step explanation:
Let the Woman's Eye level be at Band the top of the statue be at C in the attached diagram.
We want to calculate the height CE of the statue.
CE=CD+DE
First we find CD using trigonometry
Tan 60=CD/15
CD=15 X Tan 60
=25.98 ft
DE=AB= 5ft( Sides of a Rectangle)
Therefore the height of the statue
CE=CD+DE = 25.98+5=30.98 ft
=31ft( to the nearest foot)
